IMPROVEMENT IN PATENT HUDSON, WISCONSIN.

DRAFTEVENERS.

Specification forming part of Letters Patent No. 137,286, dated Aprill, 1873 5 application iled September '7, 187:2.

To all whom it may concern Be it known that I, RUSSELL BUNKER, of Hudson, in the county of St. Groix and State of Wisconsin, have invented a new and Improved Draft-Evener; and I do hereby declare that the following is a full, clear, and exact description thereof,reference being had to the accompanying drawing making part of this specification, in which- Figure l is a top view of the evener. Fig. 2 is a section taken longitudinally through the evener.

Similar letters of reference indicate correspending parts in the two gures.

To the pole-barAthe draft-pole B is rigidly secured, and across this pole lies the doubletree C. This double-tree (l has connected rigidly to it, at the middle of its length, a tongue-piece, g, which extends forward of the double-tree a short distance and is pivoted to the pole B by means of a removable vertical pin, c, which passes through an overhanging piece, d, through a longitudinally oblong slot, s, made through said tongue-piece g, and through the pole. The double-tree G is thus allowed to vibrate; and it is also allowed a slight bodily movement forward and backward. To the front end of the tongue-piece g chains J J are attached. These chains or chains and rods extend backward and outward, and are attached at their rear ends to right-angle levers 'i i, which are pivoted to short arms h h made fast to the bar A. The

inner arms of the levers i z' are connected together by a transverse rod, D, extending across beneath the pole B.

The evener which l have above described is designed for equalizing the draft when a Wheel on one side of a vehicle is obstructed; also for keeping' the tongue or pole from devia-ting to the right or left.

It will be seen that the draft of the two horses is transferred from the double-tree to the polebar A, through the medium of chains J J, levers i i, and a connecting-rod, D; consequently, when the wheel of a wagon or other vehicle is obstructed, both horses will pull on the obstructed wheel. If desirable, the chains or rod J may be connected directly to the double-tree near its extremities.

Having described my invention, what I claim as new, and desire to secure by Let ters Patent, is-

' 1. Thevibratingand bodilymovable doubletree C, connected by chains J J to connected levers t' i, substantially as described.

2. The slotted ton guepieee g on double-tree C, connected by a pin, e, to the pole B, and connected to the pole-bar A by means of 1evers c' fi, a connecting-rod, D, and arms h h, substantially as described.
